Dear Developers, I am trying to realize a use case where you can poll data from the plc at change of value. I have already seen some examples at code level but I am not a java developer and therefore I have faced some issues with the integration of the subscription mode.
i have cloned the git repository and modified [ https://github.com/apache/plc4x/blob/develop/plc4j/integrations/apache-kafka/src/main/java/org/apache/plc4x/kafka/Plc4xSourceTask.java ] locally. I would like to be able to switch in between interval polling and subscription mode, set in the configuration file. So that you can set in the configuration the PLC value to monitor and onchange it polls data. That is also why i have set in Constants.java these lies [ https://github.com/apache/plc4x/blob/develop/plc4j/integrations/apache-kafka/src/main/java/org/apache/plc4x/kafka/config/Constants.java ] public static final String KAFKA_SUBSCRIPTION_VALUE = "subscription"; public static final String KAFKA_SUBSCRIPTION_DOC = "PLC4X Subscriptionvalue"; There is also one approach i have found but couldn't adapt the algorithm correctly to my use case. https://plc4x.apache.org/users/getting-started/plc4j.html Maybe someone has had any same issues before or has already developed the PLC4xSourceTask.java? [ https://github.com/apache/plc4x/blob/develop/plc4j/integrations/apache-kafka/src/main/java/org/apache/plc4x/kafka/Plc4xSourceTask.java ] Thank you in Advance!
